Briggs 16hp cross reference question

Recommended Posts


Hey fellas,

Been working on this, slow and not so steady.... ;-)

I broke a rod / piston in my 13 hp (302431) JC Penney 7013s and with suggestions and help from here, i took the block to a machine shop. I had them bore it out to a std 16hp bore so i could buy a new piston since the oversize13hp pistons are NLA. I have a new rod and piston and a bunch of other shinny good stuff, but i need a ring set. Question is, what is the 16hp model number equal to the 302431? I had it written down and somehow lost it. All parts between the two motors were identical except the piston and rings. I think it was 326431....... Is that right? There are some ring sets on ebay and before i order, i want to make sure thats right. Thanks guys...... Of course, if any of you have a set........ ;-)

There is a set on ebay (390484) that says it was replaced by 792366. Is there any reason to not get the older 390484 set? Any difference in material or design? I assume they are just older NOS. Price is better.....

I just checked my NOS rings (both the 390484 and 390679 STD) and either will work. The only difference is the oil ring on the 390679 and is a 4 piece type with chrome rails and on the 390484 the oil ring is a 2 piece type (w/expander); both sets are chrome. The 390679 compression rings seem to have a little more spring tension though. IMHO, I would avoid an aftermarket cheapo set since you probably already invested some appreciable "cake" into this rebuild; stick with OEM Briggs rings.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
